Somerset UK quarry ID

[Aurelius]

I was having a wander in a disused quarry in Somerset (Stocker Hole, near Radstock) which is known for carboniferous fossils. Aside from one nice crinoid block, I didn't find much - but I did come across a large pile of rock which didn't look to me as if it were from that quarry. There are many quarries in the area, and it's possible that this material is spoil which was dumped in the disused quarry, but I'm not sure.

 

Can anyone offer any thoughts on the ages of these rocks? The area is known for carboniferous rock, but also contains Triassic and Jurassic layers. I examined quite a few of these rocks and didn't see any ammonites.

 

 

 

Not sure what this might be.

Sure looks Mesozoic to me - and later rather than earlier Meso, so I'd hazard a guess at Jurassic if that's the latest that occurs in that area. Let's see what others who have more knowledge of the area think....

Can't help on aging, but it looks like oyster material.

@Aurelius I'd concur with Wrangellian, but you never know, since I have no direct experience with Somerset's sediments. Have you tried asking your question at UKGE Discussions?

The area is Carboniferous. Looks like Branchiopods to me. https://ukfossils.co.uk/tag/stocker-hole/
